Pneumatic conveying defined

Similar results are reported from the drying of bark and peat in superheated steam in a pilot-plant pneumatic conveying dryer [22], The results are presented as a convective apparent heat-transfer coefficient, defined with the assumption that the temperature of the particle surface coincides with the saturation temperature of the transport steam. This transfer coefficient shows a clear dependence on the moisture content of the particles and the particle sizes. Fyhr [23] presented a model for a pneumatic conveying steam dryer. The dryer model consists of two submodels, one for the single particle and the other for the hydrodynamics of gas and particles in the dryer. [Pg.737]

Fig. 5.67 is a view (in direction A-A) of such a mixing chamber which was opened after conveying fine zinc oxide. Opposite the nozzle a deposit in a Venturi-like shape has built up which defines the most effective flow channel at this point. Similar deposits can be found along the line in pneumatic systems that were not optimally designed and/or arranged. [Pg.123]
